MEAT-SLIGING MACHINE Patented May 4, 1909.

Application filed November 10, 1908. Serial No. 461,895.

- slices by means of its peripheral edge, the

body of the knife not coming in contact with Machines of this character are fully set forth in my prior U. S. specification No. 628742 dated the 11th day of July, 1899.

The object of'my invention is the manufacture of a meat slicin machine of the foregoing class which shal be simple to construct, easy running and comparatively noiseless.

Heretofore, in meat slicing machines,

.there has been an undue amount of noise and friction during operation and a tendency for pieces of fat and grease to find their way into the base of the machine, and, on account of the diflicnlty of cleaning, to be allowed to accumulate there andbecome offensive. Owing to the improved construction of the present machine undue noise and friction are avoided and all parts can be easily cleaned and pieces of fat, etc. cannot fall down into the base;

I will now proceed to describe the invention with reference to the drawings annexed,

. whereon Figure 1 is a side elevation of the machine.

' Fig. 2 is-a plan thereof. Fig. 3 is an enlarged plan view of part of the machine and showing the frame with the meat table removed. Fig. 4 isa section taken on the line- 1 ing pad 22, and Fig. 17 a view of .the lubri- 55 eating devicefor the roller 39.

On the drawings the same reference char acters whereverrepeated indicate the same parts.

In carrying out my invention I make the machine with a base or frame 1, made with a solid top without an of the usual openings or slots therein so t at small pieces of fat, grease or cuttings of meat, cannot fall down through the base or frame 011 to the counter or become clogged in the driving mechanism. This base carries the usual drlving shaft .2 with its fly wheel and ham 1 3, and the gear 4 and 5 for driving the knife 6, and b means of the short vertical shaft 4, (whic passes through the top of the base) the crank 42 for I reciprocating the table. The table itself consists of a sliding open frame 7 comprising two side bars connected by cross pieces or bars 19, 21, and 23 and which is adapted to slide back and forward on guide rails or bars, preferably on a rectangular guide rail 8 and a. round guide rail 9, the rectangular guide rail being supported by small vertical pillars 10 and 11 secured to the base while the round rail 9 is supported upon and firmly screwed to brackets 12 and 13 on the ase.

14 is a metal plate screwed to the underside of the frame 7 and engaging the underside of the rail 8.

14, 15, 22 are metal acking pieces.

For the purpose of 111 ricating the round guide rail 9 a special lubricating deviceis provided in the frame and consists of a holder 17 (hoe also Figs. 13 and 14) which conforms to the shape of the guide rail 9 and incloses a felt or other oil pad 18 which surrounds the rail and is supplied with oil as and when required. As the oil pad surrounds the rail 9 and is also carried backand forward by the table as it reciprocates it follows that the rail is, 'kept constantly lubricated, theholder, at the same time preventin oil dripping down on to'the base. The pa holds sufiiclent oil to kee the rail lubricated for at long time. As will be seen the holder 17 is contained in a recess in the bar 19 and is removably' secured in position by a screw 20. For the purpose of lubricating the rectangular rail or bar 8 a recess 21 (see also Figs. 15 and 16) is made in the cross bar 21 of the table frame and in this recess a felt or other pad 22 is placed and is kept supplied with 0i this pad thereby,

lubricating the guide bar 8, as the table travels backward and forward.

I provide a special feed operating lever 24 which has three arms 27, 28 and 30 the arm the-machine, this connecting rod being operwheel to operate the feed screw and feed for- 30 being connected by a universally jointed l end 31 to a connecting rod 33, universally l jointed, at 34, to the lever35whieh is adapted 5 to operate the feed pawl 36 and ratchet wheel 37 of the feed screw 25. The arm 27 has a laterally projecting heel 29 while the arm 23 is curved backward and out ward as shown'at Fig. 11. This feed lever 24, which is fulcrumed on a pin 26 secured to the cross bar 23 of the tableframe, is adapted to be oscil lated by a roller 39 on a pin 40 on the con necting rod 41 which operates the table 7 of ated by the crank 42 of the driving gear. As will be seen the connecting rod 41 is connected by a pin 43 to one side of the table and underneath the same. The feed operating lever is so made, as shown at Fig. 1.1, that the feed forward of the meat commences just as the meat clears the knife on the back stroke of the table and then continues on the forward stroke thereof until the meat just touches the knife when the feed ceases, the cutting operation being then performed while the meat is absolutely stationary on the table with the result that the meat is uniformly cut throughout the length of the slice while the meat on the return movement of the table, does not press against the edge of the knife and create friction therewith. ()n the drawing (see Fig. 11,) when the roller 39 of the connecting rod 41 of the table is traveling along the curve of the jaw, formed by the arms 27, 28, of the lever 24, from the point a to d the table is traveling backward and when the roller 39 travels from the point (1 along the heel 29 and across the gap of the jaw to the point a the table is movin forward. The roller 39, at the back stro ke of the table, does not move the lever 24 until it reaches the point e when it acts on the arm 27 and moves the arm 30 and gear link 33, lever 35, and pawl 36, so as to cause the ratchet ward the meat on the table',-the forward feed of the meat being continued, while the table is traveling again on its forward stroke, until the roller reaches the point f when the forward feed of the pawl ceases. 'There is no feed of the pawl while the roller is traveling from f, to g. The back lash of the pawl takes place during the travel of the roller 39 from h to c, that is, partly on the forward travel of the table and partly on the back travel thereof.

The lever 24 may have a cylindrical hearing 57 working on the pin 26 the hearing being acted on b r a spring 58 the tension of which can be a justed by the nut 59 (Fig. 4) and which gives a yielding support to the lever 24.

Instead of using the feed operating lever 24 hereinbefore described, I may use a feed operating lever 24" such as shown at Fig. 12, which is without the second arm 28 and is 4 adapted to be operated in one direction by the roller 39 of the connecting rod 41 and in the other direction by a spring attached to the pin 6] of the cross bar 23 of the table frame.

The feed screw 25 is, preferably, provided with a small handle 44 whereby it can be operated by hand, as and when desired, so as to feed forward the meat plate.

For the purpose of quickly and nicely regulating the thickness of the meat slices, I pro.- vide the reciprocating table 7 with a bracket 45 (see also Figs. 5 and 6) in which is free to slide backward and forward a short slide bar -l(5 having connected to it a handle 47 whereby it can be operated, said handle being turnably secured to said slide bar. The handle 47 has a. reduced part which is adapted to engage with the nicks 49 of a gage plate 50 attached to the bracket 45 and each nick is numbered, the numbers preferably running from 0 to 14. The movement of the slide 46 operates a connecting rod 51 and the lever 52, fulcru'med on the end of the feed screw 25 and having a cam 53 so arranged as to regulate the action of the pawl 36 by engaging the roller 48 of the )awl and causing it to take one or more teet of the ratchet wheel 3'7 according to the thickness of slices desired. The slide -is moved by the handle 47 to the desired position and then the slide is locked by causing the handle to engage a nick 49 in the-plate 50 and as the nicks are graduated to suit'the thickness of slices, it follows that a nice adjustment can be obtained. Fig. 5 shows the iandle 47 in about the mid position so as to give slices of medium thickness the cam lever 52 being in the vertical position and the cam 53 holding the pawl out of enga ement with the ratchet wheel so that, at t e next forward throw of the awl, it will miss those teeth, in advance of it, which are covered by the cam and turn the screw 25 accordingly. In Fig. 6 the handle is shown in the last nick so as to give no feed to the screw 25 and no feed to the meat with the result t-hatmo slices are cut, the pawl being held during its back and forward throws out of engagement with the ratchet wheel by, the cam 53 which is turned around to its maximum position. lf the handle 47 is moved one nick to the left (Fig. 6) very thin slices are. given as the cam 53 only allows the pawl to feed the ratchet wheel one tooth or so at a time. It will be seen that by this simple arrangement the slices can be nicely regulated in thickness. With this arrangement no springs are used so that durability combined with simplicity is obtained while there is an avoidance of noise due to spring action. The feed mechanism can also be quickly thrown out of ac tion by simply moving the handle 47- to the zero nick.

in order to render the backlash of the pawl over the teeth of the ratchet wheel 37 silent sconce a swinging cam piece 62 is slung freely from the pin 63 of the pawl, this. cam piece being so shaped and arranged, as shown, that when the pawl is passing back over the ratchet f teeth it bears on the roller 64 and lifts the pawl out of contact with the teeth, but, when the pawl is feeding the ratchet wheel, the cam piece does not bear on the roller 64. In Fig. 7 the cam piece 62 is shown-out of contact with the roller 640n the feed screw spindle and the pawl is shown just before beginning its feed movement. In Fig. 8 the awl is shown as on its back movement an it will be seen that it is held away from the teeth-of the ratchet by the cam piece 62 hearing on the roller 64.

In order to prevent the attendant o' crating the" machine too quickly, the paw 36 is so arranged, as shown, Fig. 9, that it is automatically thrown out of engagement. 'ioeiiect this the pawl is loosely connected to the lever 35 so that, when the machine is operated very quickly, the centrifugal force engendered by the crank lever moving rapidly through an arc of a circle automatically throws back the pawl into the position shown at Fig. 9'where it is held by a support 65 on the lever 35 so as to move into working position on tlie'speed being reduced.

In order to lubricate the roller 39 on the connecting rod 41 of the driving crank, a simple device is arranged consisting of a wire spiral 66 (Fig. 17) which is secured to the cross bar 23 at the bottom of a countersunk hole 67 therein. This wire spiral contains a cotton or other Wick which is lubricated by oil in the hole 67 and is adapted to be struck by the top of the reciprocation of tie table and thereon drop a little oil into said roller andlubricate the same. I

68 is a? shaped bracket serving as a slice support.
